Prodrive Springs

Post  Abx on Thu Jan 28, 2010 6:56 am

Well first post me on our dedicated hatch forum, well done Mark

Ok, fitted my Prodrive springs at the weekend and took me about 1-1.5 hours per corner, fronts were simple as to do but the rears were a different story with just not enough room to get the shock out, what I did was use the car jack between the lower suspension arm and the chassis and push them apart, once I worked out how to do that it was pretty straight forward and the shock came straight out.

If planning to do yourself 2 things you will need is a long (2ft in my case) breaker bar to crack open the lower nuts and an open open headed socket to undo the top strut nuts, along with some spring clamps.

Really glad I went for the Prodrive springs as I don't think the ride is compromised at all, turn in is much better and the car does not lean into corners as it used to, going to let them bed in for a few weeks and then off to get my fast road geo set up sorted.

Not really dropped it much, the car seemed to always sit quite low anyway and the rear has dropped 5mm and the front 10mm.

The front was 10mm lower on one side before I started work and after installing the new springs is still 10mm lower one side, I even took the shocks off again to check all was fitted correctly and it was, so I'm guessing maybe the car is slightly heaver at the front on one side, anyone else noticed this? I even measured from the wheel centre so tyres did not come into play, rears are perfectly level.

Anyway, really happy and would recommend these 100%, If your not that handy in a garage though leave it upto a proffesional to do as can/are quite a PITA, I was getting quotes of £200 up though to fit, hence why I did myself!

Nice one Abz.

I have the Prodrive springs on mine too. I too got quotes of £300 to fit them from my dealer. I thought I'd just do it myself but then spoke to Litchfield and he only wanted a very reasonable £95 to fit them. I was getting them to do other work anyway (Rear subframe bushes, Power steering mod, Powerflex ALK and 4 wheel alignment) so it worked out perfect Cool I had already done the rear ARB.
Like you said, what a transformation. It a completely different drive now - for the better. I would say a little on the harsher side but I don't mind especially compared to my missus's Civic Type R.

Went down the same route with mine,but opted for the Tien springs(cheers Dave P)great car to drive, handles really well for me. had the fast road settings done and is spot on. It is a slightly harder ride but smoother than stock, not as bouncy?? Goin to invest in some driver training now and possibly a trip to that track in Germany Cool as its my 40th this year.

Spring rates for the hatch STi springs

Post  vulnax on Fri Mar 05, 2010 1:47 pm

Does anyone have the spring rates for the Prodrive spring rates?

I want to change my std sproings and am looking for the std and prodrive, and other makes, spring rates.

Want to tighten up the springs ( although I think the car is under damped and too weak a/r bars as std ) so the suggested Subaru / Prodrive spring rates would help.


Thanks

Neil

Neil,

I've put the ALK and 22mm bars front and rear on mine and it's made a big difference without altering the springs. Keeps it flat during cornering and still soaks up the bumps without rattling your bones.

Ok, finally got round to taking some after shots as we have not had rain or snow for a few days!!!

Standard STI Springs




Prodrive Springs




Before and after measurments came in at IIRC a 10mm drop and the front and 5mm rear, not massive but the overall stance is much better, cornering is flater and ride quality is only slightly harsher!

And a few more while I had the camera out





Cheers
Abz

Guys

I was thinking of purchasing the Prodrive spring kit.
This comes with new bumpstops aswell then?

What your opinions on them generally?
Do they reduce body roll any?

Hi Urban,

Yes, new bump stops some with the springs, at least my dealer gave me some back with my old springs.

I found on the 330S they made a noticeable difference in poise and handling of the car, less wobble on rough roads and less roll in the corners.
They remain comfortable ( a litle harsher but I now have PU bushes all round so it's more obvious! ).

I feel the understeer was reduced with the springs (although other mods needed I found to cure it for me).

Not a bad buy, around £200 + vat, but I got a £250 bill for fitting from dealer inc. 4 wheel alignment. Reasonable I guess having done this myself to my classic!


Body drop is only abbout 10mm though.

They're a definite improvement over standard for handling and yes, new rear bump stops are included. Don't drop the car by much but stance looks better as they drop the front more than the rear. And they will drop a bit more than from first fitted given a bit of use.

Save yourself some cash and fit them yourself. Hatch STi springs are the easiest to change that I've ever come across, you don't even need spring compressors. You will need a geo session after though, £60 - £65.

HTH, Neil
